Adjustable bar graders are available in the Dewatering Tower Harvesters. Different models are available for Trout, Salmon, Hybrid Striped Bass, Catfish or Tilapia. This feature is ideal for the fish farmer that needs the ability to grade fish but does not require the highly precise grade of mechanical graders. Grading gaps can be adjusted from 1/8” to 1-1/4” without the use of wrenches or other tools.

This adjustable bar grader features larger grade tubes & single grade lanes for gently grading larger fish, such as Salmon, Trout, Catfish, etc. Grading gaps can be adjusted from 3/4” to 1-1/2”. Other models also available with larger grading gaps, and longer grading tubes.
